Apparatus for facilitating access to abdominal cavity of a patient and removing larger cancerous tumors

ABSTRACT

An apparatus and method is provided for accessing an abdominal cavity of a patient via the anus for any number of surgical operations, e.g., colon cancer, appendectomy, lymph node biopsy, etc. The apparatus includes a tubular body that extends to an open end having a plurality of holes. The tubular body is inserted into the intestine of the patient, and a clamp is inserted through the tubular body of the apparatus and into the intestine. The clamp and the attached intestine is then pulled into the tubular body, so that the intestine can then be cut. The clamp and the adjacent intestine are then moved out of the tubular body so that the surgery may be performed through the intestine. The cut ends of the intestine can then be reattached (e.g., stapled, sutured, etc.) following completion of the surgery.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application for a utility patent is a continuation-in-part of a previously filed utility patent, still pending, having the application Ser. No. 17/738,430, filed May 6, 2022, which claims the benefit of U.S. Provisional Application No. 63/185,056 filed May 6, 2021.

BACKGROUND OF THE INVENTION Field of the Invention

The present invention relates generally to medical equipment. More specifically, the present invention is an apparatus for facilitating access to an abdominal cavity of a patient and removing larger cancerous tumors.

Description of Related Art

Anastomosis refers to surgeons connecting two tube-like structures inside a human body. Patients may need anastomosis to join blood vessels or sections of the bowel. Existing techniques for facilitating access to abdominal cavity of a patient and removing larger cancerous tumors are deficient with regard to several aspects.

For instance, current technologies include the application of vacuum on the inside of an intraluminal anastomotic device. Further, current technologies do not include applying variable pressure or vacuum to an abdominal cavity of a patient. When the current technologies pull the intestine into a tube, current technologies may pull in folds of the surrounding intestines unless air is allowed in next to the mouth of the tube. Putting a small amount of air near the mouth of the tube will allow only the intended intestine to be drawn into the tube. As this occurs, the intestine is inflated on the inside of the tube. This blocks the view of the cameras necessary to do the operation/surgery.

A generally similar device is shown in Vanderpool et al., U.S. Pat. No. 10,806,457, which teaches a surgical tool that has an elongate tubular housing having an annular clamping region formed around an opening in the tubular housing. A vacuum source is operably engaged with the elongate tubular housing for providing a vacuum within the elongate tubular housing for drawing the damaged or diseased portion of a luminal body, such as an intestine, into the tubular housing. An elongate rod is provided having an annular clamping element shaped so that the intestine may be firmly clamped between the annular clamping element and the annular clamping region of the elongate tubular housing, so that the damaged or diseased portion of the intestine is entirely within the elongate tubular housing.

This device is not suitable, however, for handling large cancerous or otherwise damaged tissue. Therefore, there is a need for improved apparatus for facilitating access to abdominal cavity of a patient and removing larger cancerous tumors that may overcome one or more of the above-mentioned problems and/or limitations.

SUMMARY OF THE INVENTION

The present invention teaches certain benefits in construction and use which give rise to the objectives described below.

The present invention provides an apparatus and method for accessing an abdominal cavity of a patient via an intestine. The apparatus includes a tubular body that extends to an open end, the open end having a plurality of holes disposed around the open end. The tubular body is inserted into an intestine of the patient, and a clamp mounted on a control rod is inserted through the tubular body of the apparatus and into the intestine. The intestine is then clamped with the clamp, and clamp and the attached intestine are pulled into the tubular body of the apparatus via the control rod. The intestine is then cut, and the clamp and the adjacent intestine are them moved out of the tubular body of the apparatus, thus enabling the surgeon to laparoscopically access the abdominal cavity of the patient through the intestine, for performing any procedures required. The cut ends of the intestine may then be reattached.

A primary objective of the present invention is to provide an apparatus and method having advantages not taught by the prior art.

Other features and advantages of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the invention.

DETAILED DESCRIPTION OF THE INVENTION

The present disclosure describes an apparatus for enabling access to an abdominal cavity through a luminal body (e.g., an intestine such as the colon as illustrated, or any other luminal body, such as an artery, vein, or other similar structure within a human body) of a patient and removing larger cancerous tumors, either of the intestine or other organ in the abdominal cavity. For purposes of this application, we refer to the removal of a tumor, but the term “tumor” is defined to include the removal of any deleterious material in the body, and is not limited to cancerous tissue.

Referring now to figures, FIG. 1 is a cutaway view of a tubular body 112 of an apparatus 10 in accordance with one embodiment of the present invention. The tubular body 112 is sized and shaped to be inserted into a luminal body 111 (shown in FIGS. 1A-1C, and other Figures) such as an intestine of a patient, in this case through the anus; however, other luminal bodies 111, such as arteries and veins, are also suitable, with entry being made through incisions. In the following discussion, the term intestine should be understood to include any other luminal structure in the body. The tubular body 112 extends to an open end 114 that includes a gripping element 203 for gripping the intestine 111 at the end 114. In this embodiment, the gripping element 203 is in the form of a plurality of holes which are in fluid communication with a vacuum source (not shown), i.e., a source of lower pressure which is lower than atmospheric pressure. While the holes and vacuum are used in this embodiment, other structures may be used, including mechanical mechanisms (e.g., arms, clamps, clips, etc.), chemical fasteners such as adhesives, other forms of pressure or vacuum, and non-mechanical means, and such alternative embodiments should be considered within the scope of the present invention.

As shown in FIG. 1 , in this embodiment the holes 203 are positioned in a clamping region 115, in this embodiment the clamping region 115 being an annular construction that is formed as a female section (or a female depression) between a front lip 113 and an anvil 201, both of which may be annular in construction. These features enable the plurality of holes 203, in conjunction with the female clamping region 115 in this embodiment, to form a vacuum for removably clamping the intestine 111, as described in greater detail below.

FIG. 2 is a schematic of a tip of the apparatus 10 of FIG. 1 being inserted into a luminal body 111, in this case an intestine, and access is through an anus (not shown). The tubular body 112 is inserted into an intestine 111 of the patient so that the open end is near the tumor. For purposes of this application, the term “near” is defined to mean a suitable distance for performing the operation described below, as determined by the physician.

A clamp 206 is pushed through the apparatus 10 and into the intestine 111 for clamping a portion of the intestine 111. As shown in FIG. 2 , the clamp 206 (which in this embodiment is inflatable) is pushed up into the intestine 111 until it is adjacent to where an opening is desired, at which point a gripping element 222 is used to grip the intestine 111. In this embodiment, the gripping element includes a plurality of holes 222, in recessed space as described above with regards to the apparatus 10, are used to grip the intestine 111 with vacuum. As shown in FIG. 2 , the clamp has an annular outer surface 230 that includes the plurality of holes 222, and the clamp is attached to the intestine 111 via vacuum applied through the plurality of holes 222. For purposes of this application, the term “adjacent” is defined to mean a suitable distance for performing the operation described below, as determined by the physician. While this embodiment uses holes and vacuum, other means are also available (as discussed above with regards to element 203).

A control rod 207 of the inflatable clamp 206 may be used to manipulate the inflatable clamp 206, although other structures may be used in alternate embodiments. In this embodiment, the control rod 207 includes an inner conduit 223 that supplies the vacuum to the holes 222. In this embodiment, the control rod 207 includes a connector 224 which enables the inflatable clamp 206 to be removed from the remainder of the control rod 207 to facilitate access to the patient's abdomen, and the connector includes suitable valves (not shown) that close off the vacuum source. While one form of control rod 207 is illustrated, the term “control rod” is defined to include any form of rod, tube, or control mechanism (e.g., a colonoscope) that can move the clamp 206 as required.

In this embodiment, the inflatable clamp 206 further includes locking arms 225, each attached to the inflatable clamp 206 with a hinge 226, said locking arms 225 functioning to mechanically clamp (or otherwise clamp) the intestine 111 against the inflatable clamp 206 when the control rod 207 is removed, so that the grip is not lost when the vacuum source is disconnected.

FIG. 3 is a schematic of a tip of the apparatus of FIG. 2 illustrating a clamp being used for drawing the intestine into the body of the apparatus to be cut. Once the clamp 206 has gripped the intestine 111, in this case by applying vacuum via the plurality of holes 222 as shown in FIG. 2 , the inflatable clamp 206 and the intestine 111 may be pulled into the tube 112, where a cutting mechanism 227 may be used to cut the intestine 111, typically against anvil 201, although it may be cut in any way known in the art. This process is shown and discussed in more detail in Vanderpool et al., U.S. Pat. No. 10,806,457, which is hereby incorporated by reference in its entirety.

Once the intestine 111 (or other form of luminal body) has been cut, a far end of the intestine 111A is separated from the rest of the intestine 111, and cut ends 111B (a first cut end 111B of the far end 111A) and 111C (a second cut end 111C of the near end of the intestine 111 that is positioned around the tubular body of the apparatus 10) are formed. The second cut end 111B remains gripped by the clamp 206, both by the vacuum holes 222 and also by mechanical clamp 225. The first cut end 111C is clamped by a gripping element 203.

FIG. 4 is a schematic of the tip of the apparatus 10 of FIG. 3 , illustrating the apparatus 10 once the inflatable clamp 206 has been moved outside of the apparatus 10 and aside to allow a surgical tool 208 such as a colonoscope to gain access to an abdomen through the intestine 111. Any form of surgical tool(s) may be used, either to remove a tumor as discussed below, or to perform any other surgical procedures within the abdomen.

As shown in FIG. 4 , as discussed above, the clamp 206 may be entirely removed, to allow even further access. Also shown in FIG. 4 , an annular cover 202, in this case in the form of a protector cuff, may be placed over the intestine 111 and the anvil 201 at the clamping region 115. When the protector cuff 202 (such as a silicone cap or other resilient protective material) is in position, this region is covered and protected during the performance of the rest of the surgery.

FIG. 4 also illustrates the locking arms 225 once they have been closed to lock the cut end 111B intestine 111 in place. While this combination of vacuum and a mechanical locking arm illustrates one embodiment of the invention, other gripping/clamping/fastening mechanisms known in the art may alternatively be used, in any combination deemed suitable by one skilled in the art.

FIG. 5 is a cutaway view of the apparatus with a plastic bag 204 in a collapsed position around the control rod 207 of the inflatable clamp 206, in accordance with one embodiment of the present invention. The plastic bag 204 is in a position ready to be deployed. In this embodiment, the protective cover 202 is shown exploded away from the clamping region 115, for clarity; however, it would generally be positioned over the anvil 201 and the cut end 111C of the intestine 111. The silicone cap is to protect the plastic bag 204 from the sharp edge of the anvil 201 and the folded over the intestine from the bag 204 and the inflatable clamp control rod 207. The silicone cap serves a double duty protecting the bag from the sharp edge of the anvil 201 and the intestine 111 from the bag 204 and the control rod 207.

When the inflatable clamp 206 is positioned a short distance from the tube 112, a gap 210 is formed. The tubular bag 204 is positioned around the control rod 207, so that the tubular bag 204 may now be pulled over the inflatable clamp 206 that is holding the far end of the intestine 111, as shown in FIG. 6 .

FIG. 6 illustrates the container 204, in this case a plastic bag, being pulled out of the tube 112 over the end of the inflatable clamp 206 and encircling far end of the intestine 111A. As shown in FIG. 6 , the pulling may be accomplished by laparoscopic movement, fluid movement, or any other means known in the art. Once in the bag 204, the tumor 205 may be cut up as needed so that it will fit into the tube 112 of the apparatus 10.

FIG. 7 illustrates the cancerous tumor 205 once the intestine 111A has been severed behind the tumor 205 and the plastic bag 204 has been sealed with a fastener 209 to contain the tumor 205. As shown in FIG. 7 , the tumor 205 may then be pulled into a mouth of the apparatus 10. The cancerous section 205 of the intestine 111A may be completely contained within the tubular bag 204 (or plastic bag), greatly reducing the risk of the cancer spreading. Further, the tubular bag 204 and the intestine 111 may be pulled toward the tube 112. The cancerous section 205 of the intestine 111A is now inside of the tubular bag (or a long tubular sealed bag) 204.

FIG. 8 illustrates the plastic bag 204 enveloping a cancerous tumor 205 that is too large to fit into the mouth of the apparatus 10. Accordingly, the tumor 205 can be cut down, inside the bag (or the deployable plastic bag) 204, to a size small enough to pass through the mouth of the apparatus 10.

FIG. 8 also illustrates a far end of the intestine 111D, which is the rest of the intestine beyond the tumor. This illustrates the cut end 111E, from when the intestine is separated from the tumor. This cut end 111E is eventually joined to end 111C, when the operation is completed.

In further embodiments, the apparatus may be configured for facilitating access to the abdominal cavity. Further, for accessing the abdominal cavity, a very small section of the intestine 111 is cut, forming cut ends 111B and 111C, as shown in FIG. 3 , the far intestinal section 111A is pushed out of the tube 112 leaving a gap 210 (as shown in FIG. 5 ). The gap 210 in the intestine may be used as a port for access to the abdomen. Further, the intestine, that may be folded into the tube 112, needs to be protected. To protect the intestine, small air holes are ported into the female land (female section) 115 and under the anvil 201 (or cutting anvil). When the intestinal cutter is done cutting, the anvil 201 is moved out of the way. As the anvil 201 is moved out of the way, a vacuum is induced in the air holes 203 under the anvil 201, as shown in FIG. 4 .

In further embodiments, disclosed herein is a system configured for facilitating access to abdominal cavity of a patient and removing larger cancerous tumors. Accordingly, the system may include a communication device, a processing device, and a storage device. Further, the processing device may be communicatively coupled to the vacuum source. Further, the vacuum source may be configured for inducing vacuum at the holes 203. Further, the communication device may be configured for receiving a pressure input associated with the vacuum source from at least one user device. Further, the at least one user device may include a smartphone, a laptop, a personal computer, a tablet, and so on. Further, the at least one user device may be associated with at least one user. Further, the at least one user may include a surgeon, a physician, a healthcare service provider, etc. Further, the communication device may be configured for transmitting a pressure value to the vacuum source. Further, the pressure value may be associated with the vacuum. Further, the processing device may be configured for analyzing the pressure input to determine the pressure value. Further, the storage device may be configured for storing the pressure input and the pressure value.

In another embodiment, the system is used to operate on other luminal bodies, such as vascular problems, such as aneurisms, embolisms, and the like, in arteries, veins and similar structures. In this embodiment, for example, an aortic aneurism may be treated using this system. The aorta is accessed using any surgical systems and methods known in the art, and the above-described system may be inserted for performing the removal of the aneurism as described above.
